GRAlN-DRILL.

SPECIFICATION forming part of Letters Patent No. 776,505, dated December6, 1904.

Application filed March 12, 1904.

To all whom, it Worry concern:

Be it known that we, HENRY N. Russ and FRANK E. MARSH, residents of LaCrosse, in the county of La Crosse and State of Wisconsin, have inventedcertain new and useful Improvements in Grain-Drills; and we do herebydeclare the following to be a full, clear, and eX- act description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

Our invention relates to improvements in grain-drills, the object of theinvention being to provide an improved disk bearing and improvedconstruction and assemblage of the boot, bearing, disk, and drag-bar;and it consists in certain novel features of construction andcombinations and arrangements of parts, as will he more fullyhereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation,illustrating one form of our invention; and Fig. 2 is an enlarged viewin section, illustrating our improved bearing.

1 represents a seed-dropping boot, and 2 a drag-bar secured to aprojection 3 on the boot near its upper end. An arm 4 is secured todrag-bar 2, extends downward therefrom, and is connected with abearing-block 8 for the concavo-convex disk 14:, and a scraper 6connects the toe of the boot with said arm 4t, as clearly shown. To theconvex face of the disk, at its center, a cup-like casing 7 is securelyriveted and incloses and turns freely upon the enlarged or disk-like endof a bearing-block 8. The smaller end of the bearing-block is made withan angular extension 9, fitting in a correspondingly-shaped recess inarm L, and a bolt 10 is passed through the block 8 and arm 9 and securedin place by a nut 11. Around the contracted portion of the bearing-blocka dustguard or washer 12 is located and held against arm 4: by a coiledspring 12, hearing at one end against the washer and at its other endagainst the casing 7. The washer and casing are both Serial No. 197,877.(No model.)

made with interlocking notched or toothed hubs 13, compelling the washerto turn with the casing 7 and disk 14. WVith this construction the boot,drag-bar, arm carrying the hub and scrapers are made separate andindependent, thus simplifying the manufacture and lessening the cost ofconstruction and at the same time producing a struetu'reas rigid asthose wherein the disk-carrying arm is integral with the boot.

It is evident that slight changes in the construction might be resortedto without departing from the spirit of ourinveution. Hence we wouldhave it understood that we do not confine ourselves to the exact detailsshown and described, but consider ourselves at liberty to make suchchanges as fairly fall within the spirit and scope of our invention.

Having fully described our invention, what we claim asnew, and desire tosecure by Letters Patent, is-

1. In a disk drill, the combination with a boot having a projecting lugnear its upper end, of a drag-bar rigidly secu red to said lug, adepending arm rigidly secured to said dragbar, a disk mounted at thelower end of said arm, and a scraper secured to the lower end of saidarm and to the lower end of the boot.

2. The combination with a support, of a disk, a cup-like casingsecuredto the disk, a bearing-block in said casing, and secured to the support,and a spring-pressed dust-guard around the block and bearing against thesupport.

3. The combination with a support, of a concavo-convex disk, a cup-likecasing secured to the center of the disk on its convex face, abearing-block in said cup, and made angular at one end to enter anangular socket in the support, a bolt passed through the block andsupport and secured in place by a nut, and a dust guard around the blockand bearing against the support.

4. The combination with a support, of a disk, a casing secured to thedisk, a bearingspecification in the presence of two subscribblock in thecasing and secured to the suping Witnesses. port, a dust-guard aroundthe block, inter- HEVRY N FAAS locking notched hubs on the dust-guardand FRANK 5 casing compelling them to turn together, and l a springpressing the dust-guard against the Witnesses: support.
